I was a regular visitor at the Family
Records Centre searching the civil registration index volumes (and weren't they heavy - you needed strong arms to lift them up and down all day). The information you describe was never in the indexes - you had to obtain the certificate for that.
The civil registration indexes on microfiche are images of the original paper volumes, so they are exactly the same. The searchable indexes online are transcriptions of the full entry in the original index and also give exactly the same information (barring transcription errors of course and there are many of those - always check the original image before applying for a certificate).
I hope this clarifies things for you. It is frustrating when there are several possible entries in the index and no way to tell which is the right one. 20 years ago I ordered what I thought was my gt grandfather's birth certificate and researched several generations of people who turned out not to be my ancestors after all. My gt grandpa did not have a birth certificate at all as he was born before 1875 when birth registration became compulsory - before that many births were not registered. (Hope this saves someone else making the same costly mistake).
